TLC27L7CPS Equivalent & Substitute Parts

Part Overview

The TLC27L7CPS is a CMOS linear amplifier integrated circuit manufactured by Texas Instruments, configured as a dual-channel operational amplifier in an 8-SO surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The TLC27L7CPS operates across a 3V to 16V supply range and is designed for low-power applications requiring minimal input bias current and controlled slew rate characteristics. Due to its Last Time Buy status, identification of functionally equivalent substitute components is necessary for design continuity and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC27L7CPS is determined by strict alignment of electrical and mechanical parameters within the CMOS amplifier category. The primary substitution criteria are:

Electrical Compatibility Requirements:

• Amplifier Type: CMOS (maintains identical signal processing characteristics)
• Number of Circuits: 2 (dual-channel configuration)
• Slew Rate: 0.03 V/µs (identical transient response)
• Gain Bandwidth Product: 110 kHz (identical frequency response)
• Current - Input Bias: 0.6 pA (identical input impedance characteristics)
• Voltage - Input Offset: 1.1 mV (identical DC accuracy)
• Current - Supply: 20 µA per channel (identical power consumption)
• Current - Output / Channel: 30 mA (identical output drive capability)
• Voltage - Supply Span: 3V to 16V (identical operating voltage range)
• Operating Temperature: 0°C to 70°C (identical thermal operating window)

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount (identical PCB assembly process)
• Package Category: 8-SOIC (identical pin count and electrical interface)

Compliance Requirements:

• RoHS3 Compliant (environmental regulatory alignment)
• Moisture Sensitivity Level 1 (identical handling and storage requirements)

The TLC27L7CDR qualifies as a direct electrical and functional equivalent, differing only in packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy). The LM432MA/NOPB does not meet substitution criteria due to fundamental differences in amplifier type classification, input bias current, supply current, and gain bandwidth product specifications.

Parameter Comparison

Engineering Selection Recommendations

TLC27L7CDR as Primary Substitute:

The TLC27L7CDR is the recommended substitute for the TLC27L7CPS. Both devices are manufactured by Texas Instruments within the LinCMOS™ series and maintain identical electrical specifications across all critical parameters: CMOS amplifier type, dual-channel configuration, 0.03 V/µs slew rate, 110 kHz gain bandwidth product, 0.6 pA input bias current, 1.1 mV input offset voltage, 20 µA supply current per channel, and 30 mA output current per channel. The supply voltage range (3V to 16V) and operating temperature range (0°C to 70°C) are identical. Both devices are RoHS3 compliant with MSL 1 rating.

The primary distinction is product status: TLC27L7CPS is Last Time Buy (production discontinued), while TLC27L7CDR is Active (current production). The packaging format differs (Tube versus Tape & Reel), which affects procurement and handling but does not impact electrical performance or PCB assembly compatibility. The package case dimensions differ slightly (0.209" versus 0.154" width), but both are 8-SOIC packages with identical pin configuration and electrical interface.

LM432MA/NOPB Not Recommended:

The LM432MA/NOPB does not qualify as a functional substitute. Although both are dual-channel amplifiers in 8-SOIC packages, the LM432MA/NOPB is classified as a General Purpose amplifier rather than CMOS, resulting in fundamentally different electrical characteristics. The LM432MA/NOPB exhibits 3 nanoamperes input bias current (5000 times higher than TLC27L7CPS), 600 microvolts input offset voltage (545 times lower than TLC27L7CPS), 150 microamperes supply current per channel (7.5 times higher than TLC27L7CPS), and 1 MHz gain bandwidth product (9.1 times higher than TLC27L7CPS). Additionally, the LM432MA/NOPB is classified as Obsolete, making it unsuitable for new designs or long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can TLC27L7CDR directly replace TLC27L7CPS on existing PCBs?

A: Yes. Both devices use identical 8-SOIC pin configuration and electrical interface. All electrical parameters are identical. The package case width differs (0.154" versus 0.209"), but this does not affect PCB footprint compatibility or soldering process. Existing PCB designs require no modification.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging (TLC27L7CPS) supplies components in plastic tubes for manual handling and small-quantity applications. Tape & Reel packaging (TLC27L7CDR) supplies components on continuous carrier tape wound on reels for automated pick-and-place assembly. Both contain identical components; packaging format affects procurement method and assembly process only.

Q: Why is TLC27L7CPS marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no future production is planned. Customers requiring this device should transition to the active equivalent TLC27L7CDR to ensure long-term supply availability.

Q: Can LM432MA/NOPB be used as a substitute?

A: No. LM432MA/NOPB is a General Purpose amplifier with significantly different electrical specifications. Input bias current is 5000 times higher, supply current is 7.5 times higher, and gain bandwidth product is 9.1 times higher. These differences make it unsuitable for applications designed for TLC27L7CPS. Additionally, LM432MA/NOPB is classified as Obsolete.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: amplifier type (CMOS), number of circuits (2), slew rate (0.03 V/µs), gain bandwidth product (110 kHz), input bias current (0.6 pA), input offset voltage (1.1 mV), supply current per channel (20 µA), output current per channel (30 mA), supply voltage range (3V to 16V), and operating temperature range (0°C to 70°C). All these parameters must match exactly for functional equivalence.

Q: Are there any compliance or regulatory differences between TLC27L7CPS and TLC27L7CDR?

A: No. Both devices are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance status is identical.

Q: What is the inventory status of available substitutes?

A: TLC27L7CPS (Last Time Buy) has 1027 pieces in stock. TLC27L7CDR (Active) has 2034 pieces in stock. For new designs or long-term supply requirements, TLC27L7CDR is the recommended choice due to active production status and higher available inventory.
